The table below can help you find a p-value (the top row) when you know the Degrees of Freedom DF (the left column) and the Chi-Square value...
Chi-square Value: Degrees of Freedom: P value: Rows X Columns: Chi-Square Test Introduction Chi-square test is used only for categorical variables. The summary table should only include zero or positive integers. If the total frequency is under 20 and any cell has an expected frequency ...
The chi-square table displays the critical χ2value of 1.145. This result tells us that 95% of the values are to the right of this value. Because the total area under the distribution equals 1, there must be 5% to the left of it. Hence, 1.145 is the critical value for our left-tai...
When P is below 0.01 the null hypothesis is no longer tenable. (In the majority of statistical books more extensive chi 2 tables can be found)Springer NetherlandsEncyclopedia of Genetics, Genomics, Proteomics and Informatics

About Chi-Square Distribution: In probability theory and statistics, the chi-squared distribution (also chi-square or x²-distribution) with k degrees of freedom is the distribution of a sum of the squares of k independent standard normal random variables. The chi-squared distribution is used ...

Critical Value The use of a chi-square table that we will examine is to determine a critical value. Critical values are important in bothhypothesis testsandconfidence intervals. For hypothesis tests, a critical value tells us the boundary of how extreme a test statistic we need to reject the ...
A chi square distribution on the other hand, withkdegrees of freedom is the distribution of a sum of squares ofkindependent standard normal variables. And is used in test for the independence of two variables in a contingency table and for tests fir goodness of fit of an observed data to ...
